Translated fromUnknown language

Firça tasiyan en az iki kesime bölünmüs kafaya sahip dis firçasidir serbest uç kesimi gerilim altinda olmadiginda , digerine göre 15 derece ile konumlanmis olarak eklemli bir kafayi tanimlamaktadir. Kafanin iki kesimi, birbirlerine bir boslukla bakan, oluk olusturan ince bir köprü veya mafsal bölgesiyle baglanmis uçlara sahiptir. Köprünün üst yüzeyi kafanin üst yüzüne (kil tasimayan) gömülmüstür. Birbirine bakan bitimler arasindaki bosluk 5-30 arasinda Shore A sertligine sahip elastomerle dolguludur. Mafsalli yapi, ortalama 0.5 pound firçalama kuvveti uygulandiginda, düzlesmis konuma esneyen eklemli kafayi tanimlamaktadir. Dolgu ayrica, kafa kisimlarinin alt yüzeyindeki flansta sona erebilmektedir.The brush that carries the brush is the toothbrush with a head divided into at least two sections, when the free end section is not under tension, it defines a jointed head positioned at 15 degrees relative to the other. The two sections of the head have ends connected by a thin bridge or hinge region forming a groove, facing each other with a gap. The upper surface of the bridge is buried in the upper face of the head (clay-free). The gap between the ends facing each other is filled with elastomer with a Shore A hardness of 5-30. The hinged structure defines the articulating head that flexes to the flattened position when an average of 0.5 pound brushing force is applied. Filling may also end in the flange on the lower surface of the head parts.
